text widget keeps centering without centre widget - android

image link since i'm not allowed to post images yet
I'm trying to create an app but the two texts 'hello and mr '' are in the center even when I've not added the center widget and why do they have that amount of space between them. the app title had a massive bottom padding that i had to remove it.' the app sample is in the image above.
I just want the two to stack above each other in the top left corner, and the space between them to reduce, Here's my code:
Container(
child: SingleChildScrollView(
padding: EdgeInsets.all(10.0),
child: Column(
children: <Widget>[
Text(
'Hello,',
style: Theme.of(context)
.textTheme.headline4
.apply( color: Colors.grey),
),
Text(
"Mr. Udeinya",
style: Theme.of(context)
.textTheme
.headline4
.apply(color: Colors.deepOrange, fontWeightDelta: 2),
),
Container(
padding: EdgeInsets.all(20.0),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(10.0),
color: Colors.deepOrange,
border: Border.all(
width: 3,
color: Colors.white,
)
),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(
'Wallet Balance :',
style: TextStyle(
fontSize: 19,
fontWeight: FontWeight.bold,
color: Colors.white,
),
),
SizedBox(
height: 10.0,
),
Container(
width: double.infinity,
)
],
),
),
],
),
),
),
and the image

One solution to your problem would be to change the crossAxisAlignment property of your column to CrossAxisAlignment.start
I would also recommend, if you intend to group them together, to put your two text widgets together in a column themselves.
Container(
child: SingleChildScrollView(
padding: EdgeInsets.all(10.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
'Hello,',
style: Theme.of(context)
.textTheme
.headline4
.apply(color: Colors.grey),
),
Text(
"Mr. Udeinya",
style: Theme.of(context)
.textTheme
.headline4
.apply(color: Colors.deepOrange, fontWeightDelta: 2),
),
],
),
Container(
padding: EdgeInsets.all(20.0),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(10.0),
color: Colors.deepOrange,
border: Border.all(
width: 3,
color: Colors.white,
)),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(
'Wallet Balance :',
style: TextStyle(
fontSize: 19,
fontWeight: FontWeight.bold,
color: Colors.white,
),
),
SizedBox(
height: 10.0,
),
Container(
width: double.infinity,
)
],
),
),
],
),
),
)
Something like This ? Hope that it helped.

Try to use text align property of Text widget you can find more in the link. Text widget documentation
Example:
Text("data,",textAlign: TextAlign.left,)

The problem is you are not giving a crossAxisAlignment to the top-most column, so by default, it is centred.Add this to the top-most Column
crossAxisAlignment: CrossAxisAlignment.start,

)
some notes:
try to use padding instead of SizedBox for setting padding sides. because SizedBox is using for setting spaces between something ...
crossAxisAlignment default is center if you want to make it start you should use CrossAxisAlignment.start
do not use static sizes for Container if it is not force let it fill itself
mainAxisSize default is max but here you should use MainAxisSize.min to let it use its real size of the widget.
if you had any questions i'm here.
happy coding...

Flutter: Avoid Text Widget re-centering when Timer is active

I have this flutter app with a Scaffold in which i have put the following container.
This container contains the timer's minute and seconds, and two buttons.
I am trying to avoid the Text widget to re-centers when Timer is active. This seems to happens because the Text widget changes size when a different digit is showed.
I tried to wrap the Text widget with an Expanded widget, but it didn't solve the issue. How can i solve this?
Container(
height: size.height * 0.40,
width: size.width * 0.80,
decoration: BoxDecoration(
color: Color(0xFFf4f6fa),
borderRadius: BorderRadius.circular(29.5)),
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Row(
children: [
Expanded(
child: Text(
"${f.format(_minutes)}:${f.format(_seconds)}",
textAlign: TextAlign.center,
style: TextStyle(
fontSize: 80,
color: Color(0xff7165E3),
),
),
),
],
),
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
// STOP BUTTON
Container(
decoration: BoxDecoration(
color: Colors.grey[800],
shape: BoxShape.circle,
),
height: 90,
width: 90,
child: ElevatedButton(
style: ButtonStyle(
backgroundColor: MaterialStateProperty.all(
Colors.grey[800]),
shape: MaterialStateProperty.all(
CircleBorder()),
),
onPressed: () {
setState(() {
_stopTimer();
});
},
child: Container(
alignment: Alignment.center,
child: Text(
"Annulla",
style: TextStyle(
fontSize: 14,
fontWeight: FontWeight.bold,
color: Colors.white,
),
),
),
),
),
// START BUTTON

onPressed: () {

style: TextStyle(
fontSize: 14,
fontWeight: FontWeight.bold,
color: Colors.white,

),
),
),

),
This happens because of the font you are using.
The font you use dose not have negative space. Try to use some font with negative space adjusted. I Roboto Mono is a font that have negative space.
In the above pic the characters take equal space.
pubspec.yaml
google_fonts: ^2.1.0
sport_screen.dart
Text(
"${f.format(_minutes)}:${f.format(_seconds)}",
textAlign: TextAlign.center,
style: GoogleFonts.robotoMono(
fontSize: 80.0,
color: const Color(0xff7165E3),
),
)
refer here for more about fonts and negative space.
Default Font
Monospace Font
You can use FontFeature.tabularFigures()
Example:
Text(
timerText,
style: TextStyle(
fontFeatures: [
FontFeature.tabularFigures(),
],
),
),

How to create row with multiple lines in flutter

I'm trying to replicate a flutter design that looks like this, I was able to achieve something similar by using Listtile widget, my only issue was that the leading icon didn't align vertically with the title. Please is there any other way to achieve this? I tried using a row widget but the multiple line text won't fit into the screen.
You can try this code
Container(
color: Colors.white,
padding: const EdgeInsets.all(10),
child: Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
width: 50,
height: 50,
decoration: BoxDecoration(
color: Colors.blue,
shape: BoxShape.circle,
),
child: Icon(
Icons.message,
color: Colors.white,
),
),
SizedBox(width: 10,),
Expanded(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text("Message", style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 16
),),
Text("How to create row with multiple lines in flutter How to create row with multiple lines in flutter")
],
),
),
],
),
),
Result:-
Please let me know if it work.
You can try as well as my code.
Widget ListItem({
String imageUrl,
String text,
String caption,
double imageSize = 50,
double horizontalSpacing = 15,
double verticalspacing = 20,
bool showDetailIndicatorIcon = true,
GestureTapCallback onTap,
}) {
return InkWell(
onTap: onTap,
child: Container(
margin: EdgeInsets.only(top: 2),
padding: EdgeInsets.symmetric(
horizontal: horizontalSpacing, vertical: verticalspacing),
child: Row(
children: [
ClipRRect(
child: Image.network(
imageUrl,
fit: BoxFit.cover,
height: imageSize,
width: imageSize,
),
borderRadius: BorderRadius.circular(imageSize / 2),
),
Expanded(
child: Container(
margin: EdgeInsets.symmetric(horizontal: 10),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
child: Text(
text,
style: TextStyle(
color: ColorRes.lightWhite,
fontSize: 14,
fontWeight: FontWeight.bold,
),
),
),
SizedBox(height: 5),
Text(
caption,
style: TextStyle(
color: ColorRes.grey,
fontSize: 12,
fontWeight: FontWeight.normal,
),
maxLines: 3,
),
],
),
),
),
],
),
),
);
}
I hope it's work. Please let me know.

Flutter: Uniform container size regardless of the platform (android, iOS)

Android tablet Nexus 10
but on iOS iPad I get overflowed errors
iOS iPad 8th generation
Is there a way to adjust the height and width of the containers so that they look the same on Android and iOS and do not cause overflowed errors without the aid of "SingleChildScrollView"?
Wrap each text in the _bloc1 widget with Expanded and remove the SizeBox widgets. Example, for the individual fixed SizedBox heights in your _block1 widget, they will eventually add up and cause overflow error when the total size becomes larger than available space. Also note that if your widgets are too many, things will still overflow.
Another possible solution is using FittedBox to resize your texts or contents based on available width and height.

How to add a Vertical Divider between Widget on Column in Flutter?

Good day.
I've surfed on this website about how to add a Vertical Divider between Widget on Column in Flutter? but I got nothing.
here what I want
I already make the horizontal divider. but when I try to make a vertical divider that separating between 2 objects (text | image), I got nothing.
here are the code:
Row(children: <Widget>[
Expanded(
child: new Container(
margin: const EdgeInsets.only(left: 10.0, right: 20.0),
child: Divider(
color: Colors.black,
height: 36,
)),
),
Text("OR"),
Expanded(
child: new Container(
margin: const EdgeInsets.only(left: 20.0, right: 10.0),
child: Divider(
color: Colors.black,
height: 36,
)),
),
]),
code above is for horizontal
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Row(
children: <Widget>[
Image.asset('images/makanan.png', width: 30,),
Text('Diskon 20%', style: TextStyle(fontSize: 5, color: Colors.green),)
],
),
VerticalDivider(
color: Colors.red,
width: 20,
),
Row(
children: <Widget>[
Image.asset('images/makanan.png', width: 30,),
Text('Diskon 20%', style: TextStyle(fontSize: 5, color: Colors.green),)
],
),
],
),
code above I make for Vertical Divider. but failed.
Need your help,
Thank you.
Try to replace
VerticalDivider(color: Colors.red, width: 20)
with
Container(height: 80, child: VerticalDivider(color: Colors.red))
Try this:
IntrinsicHeight(
child: new Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Text('Foo'),
VerticalDivider(),
Text('Bar'),
VerticalDivider(),
Text('Baz'),
],
))
you can either use
VerticalDivider(
thickness: 1,
color:Colors.black
),
or
Container(
height: 30,
width: 1,
color: Colors.black
)
oke here the answer.
it works for me.
Thank you mr #Android Team and mr #sunxs for your help :)
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Row(
children: <Widget>[
Image.asset('images/makanan.png', width: 30,),
Text('Diskon 20%', style: TextStyle(fontSize: 5, color: Colors.green),)
],
),
Container(height: 80, child: VerticalDivider(color: Colors.red)),
Row(
children: <Widget>[
Image.asset('images/makanan.png', width: 30,),
Text('Diskon 20%', style: TextStyle(fontSize: 5, color: Colors.green),)
],
),
Container(height: 80, child: VerticalDivider(color: Colors.red)),
Row(
children: <Widget>[
Image.asset('images/makanan.png', width: 30,),
Text('Diskon 20%', style: TextStyle(fontSize: 5, color: Colors.green),)
],
),
],
),
you can try:
Container(
color: Colors.grey,
height: 30,
width: 1,
),
It worked for me! :))
The most optimal way is to put the Vertical Divider inside a SizedBox.
SizedBox(
height: 80,
child: VerticalDivider(color: primaryColor),
)
